Viruses
Some of the more harmful chain letters and hoaxes have transmitted viruses across the Internet.
The best way to guard against catching a virus through e-mail is never to open an attachment to an e-mail message, especially if the attachment has an executable filename extension such as .exe, .vbs, or .class.

Lurking
To lurk means to participate in a conversation on the Internet without responding to any of the messages.
You receive and read the messages, but you don’t say anything in return. Thus, you’re lurking!

Flames
On the Internet, a flame is a message written in anger.
To flame someone is to send them an angry message.
Angry messages that people send you are known as flames.
If you are real mad and send a hastily written flame, you may regret it later on.

Firefighters
Sometimes flaming can get out of hand. People start sending more-heated
messages, and things can get ugly. Someone has to step in and write a
message intended to restore peace. Since that puts an end to the flames,
such peacemakers on the Internet are known as firefighters.

Smileys and Emoticons
To give the person reading your message a clue as to what your emotions are, emoticons were invented.
Emoticons are combinations of a few characters which, when turned sideways, conjure a facial expression.
The most common form of emoticon is the smiley. :-)
